Abstract

To regenerate binary information from a perturbed baseband signal, particularly a D2-MAC signal, an automatic gain control signal for an automatic gain control amplifier (V) is derived from a peak-value detector (SD1, SD2). The signal components which are outside this data burst are gated out during the gain control process. Due to these measures, the position of the data burst is optimally aligned with respect to the decoder decision circuit thresholds (E1, E2). <IMAGE>
